Mine sat because of a bad starter and because I had another Supra. Other Supra developed a head noise so finally I laid in the driveway in leaves and sticks and busted knuckes getting the starter changed from below. Penetrating oil in the jugs overnight in 4 of the 6 cylinders, cranked it pushing oil out the next day, put the old plugs back in and added 2 gallons fresh fuel and it's alive showing a third of a tank of basically paint thinner at this point and its kicking topped off coolant with water for now till I do a flush. Critters had built a nest in left side of exhaust blowing out the muffler so I will need a muffler. Tires were still good but who knows for how long, a relief cause tires cost money for this car.

Scared the shit out of me because it started blowing steam out of the exhaust on a round the block trip, happened as I was going up a large hill. Has cleared out now so I am guessing it had some water in the exhaust. Runs like a car on 8 year old gas and old plugs looking forward to fresh gas and a nice run down these WV windy roads.

Not sure yet, it could be a timing issue or it could be a broken valve spring. Not sure. I have it to some degree on both my cars. One fella told me he put a washer in between the distributor tightening adjustment bolt and the head to make the distributer pull slightly away from his head and this took it away from his. Others have mentioned it could be arcing plug wires or spark knock from incorrect timing. I have been working on the Red Supra. my Black 87 is the one with the loud noise. Once I finish getting the Red one road worthy I will try to find time to work on my black one. Doing the exhaust and tires now.

thanks, that sorta helps, the guy who rebuilt the motor torld me he thinks its a rocker, but with all the things up with it right now theres no telling, and i am in the same with the tail pipe stuff mine is only half way back off the turbo so i have to get a custom one made, and i got a oil leek from somthing to, the life of a supra owner is not a cheap one i guess

OK BIG RED FLAG! If the guy that told you he rebuilt this motor said he thinks the noise is a rocker you have a big problem. This motor does not use rockers nor does it have any. The cams ride on top of the valves. There are no rockers!!!! This guy is feeding you a line of crud.
